What is the Low Oil Level Sensor all about?

The vital role of the low oil level sensor is protecting your engine from friction as well as wear and tear. You need to have the right amount of oil in the engine at all times or the friction and heat will severely lower the longevity of your engine components. Today, most cars come with an oil level sensing system that determines how much oil is in the pan and transfers the information to the car’s computer. If the level is too low, the computer turns on the Low Engine Oil light on the dash, warning the driver of the problem.

The low oil level sensor is attached to a float type device in the oil pan. It measures the amount of oil present in the pan during operation. Depending on the position of the float, the sensor knows how much oil is present and sends the data to the computer. The computer compares that information with the preprogrammed readings from the automaker and determines if it’s sufficient.

Keep in mind:

  • The Low Engine Oil light is located in the dash gauge cluster and should come on for a few seconds after you initially crank the engine.
  • If you get erratic warning lights in the dash, but the level of the oil in your pan is normal, the low oil level sensor is likely the culprit.
  • The low oil level sensor is not an included part of any normal inspection.

How it's done:

  • The vehicle is lifted and supported on jack stands and the oil and filter are removed
  • The defective low oil level sensor is removed
  • The new low oil level sensor is installed
  • The vehicle is removed from jack stands then oil and filter installed
  • The vehicle is started and checked for oil leaks and level operation

Our recommendation:

Maintaining the right oil level in your engine at all times is absolutely crucial. If the low oil level sensor in your engine is malfunctioning, you have no way to determine if there’s a problem. If the oil level does drop too low, there’s the potential for significant damage. Have one of our expert mechanics diagnose the system if you suspect a problem.

What common symptoms indicate you may need to replace the Low Oil Level Sensor?

  • Low Engine Oil warning light on in the dash, even when the level is correct
  • Erratic warning lights when level is full
  • Light comes on and stays on when oil is full

How important is this service?

While the low oil level sensor isn’t critical to engine operation, it is an important safeguard. If you’re experiencing any problems with the light and suspect that the sensor is to blame, have our expert mechanics diagnose the problem.

BMW 545i V8-4.4L - outlet coolant temp sensor - Union City, California
Mark has been excellent, jumping into the mess created by another mechanic (which is why I'm hesitating to recommend the company now), and got it straightened up. He's very professional, and communicates timely. I'm trusting him for my other cars!

I was hopeful he would be able to adjust parking brake but was unable to do so due to a locked up star adjusting nut. Will have to get towed to a shop to have fixed.
